Another object of the invention is to provide a machine of the type indicated having separate donning and dofling mechanisms for each spindle of the group with the operation of the individual mechanismstimed and controlled by an electrical device common to both. I

Another object of the invention is to provide a machine of the type indicated having means adjacent each spindle of the group of winding units and adapted to be engaged and moved by the winding strand when the bobbin reaches a predetermined size to initiate the donning and group.

Another object of the invention is to provide a machine of the type indicated in which thedonning and doiiing mechanisms are actuated by electromagnetic means whereby to simplify the construction of the machine by eliminating mechanical elements liable to become deranged or to get out of order.

Another object of the invention is to provide a machine of the type indicated having improved driving mechanism capable of operating the winding units at a higher rate of speed than is possible with similar machines of previous types.

Another object of the invention is to provide a machine of the type indicated in which the spindle-drive and thread-guide reciprocating means are operated continuously during the preferred form of construction of the machine,

The present improved winding machine comprises, in general, means for winding bobbins or the like, including bobbin-rotating means and yarn-traversing means, means actuated by the yarn or thread being wound. when the bobbin reaches a predetermined length for initiating the dofling of the completed bobbin, means controlled by the released wound bobbin for returning the thread-guide to initial position, a magazine or hopper for containing a supply of empty bobbins, means operable after the thread-guide has reached its initial position for transferring a fresh bobbin from the magazine to winding position, means for rotatably gripping the fresh bobbin, means for severing the yarn leading from the previously wound bobbin. means for retrieving the yarn and clamping it to the fresh bobbin, means initially set by movement of the bobbin-transferring means and actuated by the yarn-traversing mechanism of the winding unit for winding a bunch on the bobbin, and means i for releasing the yarn from the bunch-building More specifically, the present embodiment of the invention comprises a series of pairs of wind.- ing units arranged along a frame, each unit of the pairs consisting of a continuously rotated spindle-cup for receiving the butt end of the bobbin or yam-carrier and a freely rotatable stub-spindle for supporting the tip end thereof. Continuously reciprocating traversing means actuate the thread-guides, one for each unit, with means for advancing the guides along the bobbins as the latter-are wound. Means engaged by the yarn when either bobbin of the pair reaches a predetermined length operate to close an electrical circuit, common to both winding units, to energize means for shifting the spindle cups axially to release the bobbins and permit them to drop into chutes arranged below the windingspindles. Means within the chutes are actuated by one or the other of the falling bobbins to close a second electrical circuit, also common to both winding units of the pair, the latter circuit serving to energize electromagnetic means for returning both thread-guides to initial position. An electrical time-control unit in the' form of a spring-actuated rotary drum-switch controls the action of the electromagnetic means for operating the spindle-cups and the means for transferring fresh bobbins from the magazines or hoppers to the respective spindles. Through an escapement device actuated by the constantly reciprocating yarn traversing means the spring-actuated drumswitch is permitted to rotate to again open the circuits. When the electromagnetic means for withdrawing the spindle-cups are deenergized the cups are caused to rotatively grip the fresh bobbins and thereafter the bobbin-transferring means are shifted into inoperative relationship. The yarns trailing from the thread-guides to the previously wound bobbins are gripped between the spindle-cups and the end of the bobbins and are also clamped at a point between the fresh bobbins and the previously-wound bobbins so that as the fresh bobbins are rotated the threads or yarns are severed. Means are provided for withholding the yarns from traversing movement with the reciprocating thread-guides at the start of the winding whereby to wind so-called bunches or reserve lengths of the yarn, the bunch-building means being set in initial pos tion by the actuation of the bobbin-transferring means and caused to release the yarns by the operation of an escapement mechanism actuated by the yamtraversing mechanism. In the following detailed description of the machine the various cooperating mechanisms are described under separate headings.

It is customary in winding machines now in use to employ a plurality of winding units arranged in gang form along either side of the machine frame. In the present machine the winding units are provided at both sides of the frame but are arranged in separate groups, in this instance, in pairs of units, with each unit of the pair embodying individual donning and dofling mechanisms with the ,mechanisms of both actuated simultaneously. Since the several pairs of winding units are identical in construction and arrangement only one pair is herein shown and described.

Winding units and drive therefor Referring first to Figs. 1, 2 and, 3 of the drawings, the winding units of the machine are carried by a horizontal bed 2, usually supported from the floor by legs or standards 3. Mounted upon the .bed 2 are trough-like casings 4 in which the various driving elements are enclosed. Journaled in bearings in the opposite end walls of the casing 4 are two drive-shafts 5 and B which may be rotated by suitable means located at one end of the machine frame, but not herein shown. The shafts 5' and 6 drive the individual winding- .spindles 9 and III which are journaled in bearings in the side walls of the casing 4 and project laterally therefrom; In the present drawings four spindles 9, III, II and I2 are shown as journaled in the casing 4, one pair of spindles 9 and I0, projecting'from the left-hand wall, as viewed in Fig. 1, and the spindles H and I2 of the opposite pair projecting from the opposite wall. Since all the spindles are of the same construction and arrangement only one pair (9, ill) will be herein described. The spindles 9 and I0 are journaled in bearing bosses l3 and 14 on the sides of the casing 4, the bearings being shown in detail inFigs. 2 and 4. An annularlyrooved enlarged head l5 at the forward end of each spindle forms a shoulder which abuts the recessed end of the bearing l3 and a collar H5 at the opp'osite end of the bearing abuts the side of an arm i1, formed as a part of a braoiketfll to be glescribed later, to take the axial thrust of the spindle in opposite directions. The rearward end of each spindle is journaled in a bushing iii in" the boss l4 and the end of the boss is closed by means of a plug or cap l9. a

The drive-shaft 6 carries a series of helical gears 20 which mesh with smaller similar gears 2| freely rotatable on the spindles 9 and I0, see Fig. 2. The gears 2| are held against axial movement in one direction by collars 24 secured to the spindles and against movement in the opposite direction by sleeves 25, also secured to the spindle. Keyed to each sleeve 25 and arranged for axial sliding movement thereon is a clutch-member 26 having a tapered periphery adapted to engage The clutch-member 26 may be shifted manu ally to release it from engagement with the gear 2| by means of a curved finger 30, see Fig. 2, having its side formed with an inclined edge, shown in Fig. 1, engageable with the side of a substantially V-shaped annular groove 3! in the clutch-member. The finger 30 is formed integral with arockable member 32, shown most, clearly in Fig. 2, having its rearward end journaled on a stud-33 in the side wall of the casing 4. The forward end of the member 32 is joined to a horizontal rod 34 by means ofta coupling 35 shown in detail in Fig. '8. The forward or outer end of the rod 24 extends through a bearing in the upright arm 26 of a bracket 31, to be described later, and is bent at right-angles to form a handle 38 for rocking the clutch-control member 32. The bracket 31 is attached to the casing 4 by means of a nut 39 screwed onto'thethreaded extremity
